摘　　要：氧化锆陶瓷拥有高的强度、硬度、断裂韧度以及耐高温、耐腐蚀等性能,在3C电子、生物医疗、化工、机械、新能源等领域有着广泛的应用。但氧化锆陶瓷器件磨削加工效率低、工具磨损严重,难以获得高的表面质量。磨削加工过程中冷却润滑方式对氧化锆陶瓷加工效率和表面质量有着重要影响。文章研究了不同纳米粒子微量润滑条件下电镀金刚石工具磨削加工对氧化锆陶瓷的磨削力和表面质量。结果表明添加纳米金刚石、石墨烯、MoS2纳米冷却液的微量润滑条件下可以降低氧化锆陶瓷的磨削力,其中MoS2纳米冷却液的磨削力最小;而使用浇注式冷却条件下的法向磨削力最大,干式磨削条件下的切向磨削力最大;不同冷却方式加工的氧化锆陶瓷的表面粗糙度差异不大。Zirconia ceramic(3Y-TZP)is widely used in 3C electronic,biomedical,chemi-cal,machine,new energy,and other fields due to its high strength,hardness,fracture toughness and excellent thermal and corrosion resistance.However,the grinding process for zirconia ceramics often suffers from low efficiency and significant tool wear,making it challenging to achieve a high surface quality.The cooling and lubrication method em-ployed during the grinding process plays a crucial role in affecting the efficiency and sur-face quality of zirconia ceramic machining.The article studied the grinding force and sur-face quality of zirconia ceramics during electroplated diamond tool grinding under different nanofluid minimum quantity lubrication conditions.The results indicate that the addition of trace amounts of nanofluids containing nanodiamonds,graphene,and MoS2 reduces the grinding force for zirconia ceramics,with MoS2 nanofluid showing the lowest grinding force.In contrast,under flood cooling conditions,the normal grinding force is the high-est,while under dry grinding conditions,the tangential grinding force is the highest.The surface roughness of zirconia ceramics processed under different cooling methods exhibits minimal differences.
